Why Choose the IMO UB10C3030A Miniature Circuit Breaker?
The IMO UB10C3030A is a robust three-pole miniature circuit breaker (MCB) designed to protect industrial electrical circuits against overloads and short circuits. As part of the dependable IMO UB10 circuit breaker series, it provides effective branch circuit protection for machinery, control panels and three-phase electrical distribution systems.
This circuit breaker features a C curve tripping characteristic, making it suitable for circuits supplying equipment with moderate starting currents, including motors, transformers, contactors and industrial control devices. Its thermal-magnetic operating mechanism provides automatic disconnection during sustained overloads and high-current fault conditions.
With a rated current of 30 A, a three-pole configuration and a 10 kA short-circuit breaking capacity, the UB10C3030A is suitable for demanding industrial installations. Its compact DIN rail mounted format enables straightforward integration into electrical enclosures, machinery cabinets and distribution assemblies.

Reliable Circuit Protection for Industrial Systems
Miniature circuit breakers automatically isolate an electrical supply when excessive current is detected. This helps protect cables, machinery and connected equipment from damage caused by overloads, short circuits and other electrical faults while improving operational safety and system reliability.
The C curve response of the IMO UB10C3030A allows it to tolerate temporary current surges during equipment start-up while maintaining effective protection against genuine electrical faults. Its three-pole switching mechanism disconnects all protected phases together, making it suitable for three-phase machinery and power circuits.
Typical Applications
- Industrial control panels and electrical cabinets.
- Three-phase machinery circuits.
- Motor and transformer supply circuits.
- Factory automation and production equipment.
- Commercial and industrial distribution boards.
- OEM machinery and process-control systems.
